4.6.2 Power meter function
The power meter function can be activated for each channel and can be parameterized further
afterwards:

The power meter counts the active energy of the channel according to the adjusted voltage and the
measured current. The intern count is continuous but the output rises only up every 10Wh.
Via the object "Reset power meter", the power meter can be set to zero again.
So the power meter function offers an effective method for observing the power consumption of
devices at determined cycles (day, week, month). An additional visualization of the power
consumption can help saving energy and switch devices on demand.
The following chart shows the relevant communication objects:
